FLEXIBLE PIPE-UNION.

Specification of Letters Patent.

Patrnte d April 21, 1908.

of Perinsylvaiiiia,-have invented new and use {cl Improvements in Fiexible Pipe-Unions, of which the following is 'a {specification The-object of my inven tion is "to provide a ,new and improved Iiiexihle pipe union, and .j to thisend-rny invention consists of a flexible pipe-unio'n, in thefnovlieatnres of construction and in the combination ofdparts all as hereinafter described and claims In the accompanying drawing, which illustrates applications of my invention, Figure 1' is a central verticelsectional vicwo'f a union constri'icted in accordance with my invention showing the union assembledior use with liquids: Fig. 2, a similar'viewwiththe bearing-ring reversed and the union assembled for use with steam: Fig. as central vertical sectional View of a modified form of union with the parts assembled to constitute a.tight "nn1on': and Fig. 4:, a similar view .of 'the'modified form showing "the parts assembled as a .loose union.

Referringto the drawings, 1 designates a socket member, .2 a ball-member, and 3 the cap or closing-member, of the flexible union 1 As illustrated the socket-member com- I prises an internally ,screw threaded nozzle 4 and is formed with an annular recess 5.

Recess 5 is formed by an annular shoulder 6 ends; wall 7. The upper end of the socket- "member is externally threaded, as shown at 8 and is constructed with aseat -The hollow' closing or cap-member 3 isvinternally screw-threaded at 10 to engage the exter- .naliy threaded portion 8 of the socket-member. Cap-member b is formed with an irregular recess or a recess varying in diameter, the lower portion 11 being oi greater diameter than the upper portion 12.

13 designates a bearing-ring. This ring is formed with an exterior annular flangedportion 14, and a concave inner bearing-surace 15. Ring 13 constitutes a characteristie and important feature of my invention, and the'function of said ring is to change the relative positions of the ball-anrhsockctmemhersof the flexible union in order to nrovido'a ii ht joint or union, particu- Emir adapted 219F188 with liquids and to pro vide a loose joint, the latter being particularly adapted for use with steam.

Fig. 1 shows the parts assembled as a tight union and in this case the flangedportion 14 of the bearing-ring is located in the widest portion 11 of the irregular recess of the cap-member and the remaining portion of the ring located in the annular recess of the socket-member. In the form of Fig. 2, the ring is reversed to form a loose union and in this instance is entirely locatedin the irregular recess of the cap-member. In both cases the flanged ortion of the ring is locatedin portion o the recess of the cap-member. A l evers'al of the ring from the position shown by Fig. 1, to the position shown by Fig. 2 raises the socket-member slightly, thereby forming a loose union.

In the form of Fig. 3, the socket-member is formed with a bearing-seat 16 and the ball member in this form has its bearing on said seat 16 instead. of on the bearing-surface of in Fig. 1, the flanged-portion is greater above the center line. 7

Particular attention is called to thefact that whenthe parts of the union are assembled for a' loose union orfor use 'with steam, the entire bearing and wear comes on the removable reversible ring.

l/Vhat I claim is: v

1. A flexible ipe-union comprising a ballmember, a soc et-member formed with an interior annular recess, a cap-member, formed ,with an interior annular recess varying in diameter, and a reversible flanged bearmgring having its'fianged portion located in the recess of the cap-member.

2. A flexible pipe-union comprising a ball et-member f orined' with an interior annular recess, a cap memberifornaed member, a soc with an annular recess varying in diameter, and a reversible flanged 'bea'ringhaving its flanged portion located in the 'w' est portion of the recessof the ,ca mem In testimony whereofI- 1X my signature, in presence of two subscribingiwitnesses.
